To ALL wHoM 1r MAY ooNcERN;

Be it known that I, Brennan' TATrEnsHALL, of Beloit 'Rock county, State of Wisconsin, have invented certain new and useful Improvements in Spring-Bed Bottoms; and I do hereby-declare the following description and accompanying drawings are suiiicient to enable any person `skilled in the art or science to which it most nearly apport-.tins :to maker and use my vsaidinvention or improvements without further invention or experiment. i

The nature of my invention and improvements consists in constructing a spring-bed bottom as shown by the accompanying drawings, in whichv Figure 1 is a perspective view ofthe top' elevation of a bedstead provided with my improved spring-bed bottom.

Figure 2is a side view of the sume. 4

Figure 3 isa transverse section of the .end of the bedstead or .end-board, also having bracket-hook E detached.

Figure 4 is a similar view of the supporters' C; and` Figure 5 is a view of the rubber band B, with the guard-band H detached.

Similar letters of reference indicate like parts.

In the drawi-ngs, D represents the bedstead-frame, A the sla-ts, B the endless-rubberspring bands, H the guard or safety-bands, asl shown in iig. 5. Q are supporting-bars resting in the hooks or brackets E, held in position by the lock-pin e, as shown in iig. 3. are a series of hooks, on'which are suspended the rubber springs B and guard-ban`dsHg and I is a transverse slat passing centrally under` the slats A, secured thereto by a suitable band of webbing tacked thereto 'over and between each slat, and supported by rubber springs B, guard-bandsH, and hooks 6. In general, I construct my improved bed-bottom with eight longitudinal slats, (any available number may be used, more or less,) with one transverse slat centrally, as shown. nThe ends of thc slats are inserted' into and through the rubber-band springs B and guard-bands H. I use slats two inches wide and ivc-eighths of an inch thick. The transverse end-supporters C have a'series of hooks, b, equal to the number ci'V slats used, which hooksl have one end inserted through the supporters C', and secured thereto by a cap-rivet, as shown, figx4. The lower angle of said hooks should come about even with the under surface oi' the supporter` C, (the drawing in this respect being in error,) so that when the rubber bandsnre placed on the said hooks the slats may pass under them.. II make the supporters C two inches wideand three-quarters of an inch thick, lof hard pine or hard-wood timber. The'uppere'nd of` the bracket E isimade at anV angle, so as to hook into a suitable hole bored in the end of the bedstead D. A small pin, c, is inserted in a hole drilled through the back of the bracket and bored in the wood, thus cli'ectually locking the bracket tothe end-board ofthe bedsteud, as shown in ig. 8. The supporters C aredropped into the said brackets, and thereby securely held. I employ two of said brackets at each end of the bedstead, las shown at E in iig. 1. The guard-bands H are of webbing, (about one inch widc,) or other suitable material, the ends rmly'held and joinedby eyelets or otherwise, as most convenient, and are placed oversand around tlie rubber-spring bands of suitable length`to prevent undue straining or breaking of the said rubber springs. Y I make these bands long enough to allow the rubber springs to strctchrabout three inches vertically. Even should one or morefof said springs break'no inconvenience canV happen to the sleeper. I make the r'ubbcr bands one inchl wide, of tubing one-eighth inch thick and vc inchesV circumference inside; -the rubber tobe of best quality. The hooks bare made of three-i sixteenth braziers rods, and bent, cold or heated, to the required shape.

This bed-bottom may be"'made with or without thcsprings on the transverse slat I, or that also may be omitted. Cheapness and simplicity of construction, convenience for use, and facility of manipulation in adapt ing it to any ordinary bcdstead, with ease in putting up and taking downare characteristic of this invention. Not a nail or-scrcw is required in its construction'or use. i

I claim the employment of the device herein described for securing the supporters-C t0 the bedstead D,`

as set' forth.

I also claim` the'guard-bauds H, or their equivalent, in combination with the supports C, brackets E, lockingpins e, hooks b, the transverse slat I, rubber springs B, and slats A,`when constructed and arranged substantially as herein set forth and described, for the purpose specified. Y

RICHARD TATTERSHALL.
